Parallel Cable IV not detecting

simple question... IMPACT doesn't recognize my xilinx parallel cable IV when downloading projects to the board. I have read in some articles that a power supply is necessary to power up the cable, but there is no power supply or adapter in the box where the

cable came.

------Can any one tell me what do i do? as my laptop does not have the socket for the pin that is with parallel cable IV... which i think may be for powering up the cable

-----and it also says Checking cable driver. File C:\WINDOWS\system32\drivers\xusbdfwu.sys not found. There was no driver cd withthe virtex -II pro xc2vp7 board...where do i get this xusbdfwu.sys file...

Thanks in advance from this starter. attached is the error i get when i am trying to connect the cable to download the stream to board. Regards

The dongle gets its power from the target board.

False. Prallel Cable III getsi its power form the target board, but thisi is not true for Parallel Cable IV.

Parallel IV cable gets its power form one of two sources:

- PC Ps-2 connection. The cable comes with an adapter for this. It is normally enough, unless you are connecting the PCIV to a portable. In such case, use next option.

- External adapter. I think it was a 5V DC, 0.5 Amp adapter (chek it in the docs!). You may buy it almost anywhere, it is pretty standard.

The most imprtant thing: You will be unable to connect to PCIV unless its light is on (orange or green colour/color).

Usually the Parallel Cable IV comes with a PS2 (keyboard/mouse) type cable that you put between your keyboard and your PS2 socket. This is a major problem with most laptops as they don't have a PS2 socket. In part this is why Xilinx have now produced a USB cable.

Easiest solution is to buy a mains adaptor with a suitable jack. You only need a 300/500mA type adaptor and you can usually buy multi-voltage, multi-head adaptors for about £5-10 (US$9-18). If this isn't a good solution you can sometimes get a USB to PS2 adaptor that can supply the 5V needed.

Other cheap ways to solve your problem are to get hold of a suitable Parallel Cable 3 look-alike. Available from various manufacturers including ourselves but check the connection type as most don't have flying leads, or the 14 way 2mm cable.

Ah, sorry 'bout that, Chief. I just looked at the Parallel Cable III (is this like Led Zeppelin III?) sitting here and assumed that the IV was similar.
